Detailed Description

template<typename... ArrayHandleTypes>
class viskores::cont::ArrayHandleMultiplexer< ArrayHandleTypes >

An ArrayHandle that can behave like several other handles.

An ArrayHandleMultiplexer simply redirects its calls to another ArrayHandle. However the type of that ArrayHandle does not need to be (completely) known at runtime. Rather, ArrayHandleMultiplexer is defined over a set of possible ArrayHandle types. Any one of these ArrayHandles may be assigned to the ArrayHandleMultiplexer.

When a value is retreived from the ArrayHandleMultiplexer, the multiplexer checks to see which type of array is currently stored in it. It then redirects to the ArrayHandle of the appropriate type.

The ArrayHandleMultiplexer template parameters are all the ArrayHandle types it should support.

If only one template parameter is given, it is assumed to be the ValueType of the array. A default list of supported arrays is supported (see viskores::cont::internal::ArrayHandleMultiplexerDefaultArrays.) If multiple template parameters are given, they are all considered possible ArrayHandle types.
